Pro tips

  1. 01

    Trail-Ready Shoes

    The course runs on well-kept forest trails through meadows and ponds, with asphalt only in the local area. Wear trail shoes or road shoes with grip for packed natural surfaces.

  2. 02

    Cool Start, Warm Effort

    Typical race-day temperature is 13.9°C. September in the Harz can feel chilly before the start; use layers you can shed once you warm up on the trails.

  3. 03

    Pond and Mining Heritage

    The route passes the Upper Harz water-management ponds that once powered mine water wheels. Expect historic water channels and uneven ground; keep eyes on footing while taking in the scene.

    Stay for Après

    The description highlights the après-marathon as part of the experience. Plan your day so you can linger after finishing rather than rushing off.

    Local Forest Loops

    The race stays in the Hahnenklee local area, so you won't face a long transfer to remote trailheads. Expect a compact, nature-focused route through forest, meadow, and pond country.
